| Popis: | Leaf secondary metabolites production and physiological leaf traits were analyzed in Corylus avellana wild type (WT) and cultivar (cv. ‘Tonda Gentile Trilobata’, TGT) under different nutrient supplies. Three treatments were applied: control treatment with no fertilizer supply (WTC and TGTC), low nutrient treatment (WTLN and TGTLN) and high nutrient treatment (WTHN and TGTHN). The analysis of leaf extracts showed a higher concentration of Quercitrin and Myricitrin, with the highest concentrations of both the compounds in WT than TGT. This result can be related to the ecological role of flavonoids, including also antimicrobial properties, which resulted more useful in the understory forest form which hazelnut wild type originates. Therefore, their lower concentration in TGT can be relate to the genetic background of TGT cultivar with a lesser intrinsic need to produce such compounds and justified by a usual growth under more controlled environmental conditions, including also pest and disease control. |
